I have what you are looking for.
Total weight - 14 oz, Apex 2.5 with M50 outer Nobul2 inner and a little M90 for strength on the foot area (made for keeping shoes on). There is even a little down in the 6 inch vertical draft tube that tucks under you.
It will fit someone up to 6 feet.
I am 5' 11" and it is just slightly tight.
If you're 5' 10" or less, you would be good to go.
It is a slightly different design than a normal.
The foot box is sewn with no insulation on the bottom and has a 3D footbox.
It goes out to about 54" so there is plenty there to wrap around you.
There is even a single layer extension to help it stay tucked in.It is also sewn back onto itself about 6" from the corner.
It really helps as when you tuck you shoulders in them, they stay under.
I just noticed a small burn mark in it.
I did something similar for a sub 10 ounce quilt and love my quilt.. Much warmer that a standard quilt, but all you have to do is take your shoulders out if it's to warm. Works great.
I made this for a friend as a quick nap system for thru hike speed attempts, but ended up with it.
I've used it about 5 times and it just got washed. I can fix the burn mark if you want but it doesn't effect anything.
It's kind of melted to the apex.
Yours for $90 shipped.
